IHydroxypropyl methylcellulose(HPMC) i-nonionic cellulose ether elungiselelwe uchungechunge lokucutshungulwa kwamakhemikhali kusetshenziswa i-cellulose ye-polymer yemvelo njengempahla eluhlaza. Ziyimpushana emhlophe engenaphunga, engenaphunga, engenabuthi evuvukala emanzini abandayo ibe isixazululo se-colloidal esicacile noma esithe ukuxubeka. Inezici zokuqina, ukubopha, ukusabalalisa, i-emulsifying, ukwakheka kwefilimu, ukumiswa, i-adsorption, i-gelation, umsebenzi ongaphezulu, ukugcinwa komswakama kanye ne-colloid evikelayo. I-Hydroxypropyl methylcellulose, i-methyl cellulose ingasetshenziswa ezintweni zokwakha, imboni yokumboza, i-synthetic resin, imboni ye-ceramic, imithi, ukudla, izindwangu, ezolimo, amakhemikhali nsuku zonke nezinye izimboni.
I-Hydroxypropyl methylcellulose (HPMC) Isibalo samakhemikhali:
[C6H7O2(OH)3-mn(OCH3)m(OCH2CH(OH)CH3)n]x

(1) Thuthukisa ukufana, wenze ukhonkolo ulugcobe kalula, uthuthukise ukumelana nokuntenga, uthuthukise uketshezi nokudonsa, futhi uthuthukise ukusebenza kahle komsebenzi.
(2) Ukugcinwa kwamanzi okuphezulu, ukwandisa isikhathi sokubeka udaka, ukuthuthukisa ukusebenza kahle komsebenzi, kanye nokwenza lula amandla aphezulu emishini yokufakwa kwe-mortar nokuqiniswa.
(3) Lawula ukufana kokungaguquguquki kodaka ukuze kwakheke ukunamathela kwendawo oyithandayo.
3. Udaka lwamatshe
(1) Thuthukisa ukunamathela endaweni engamatshe, uthuthukise ukugcinwa kwamanzi, futhi ukhulise amandla odaka.
(2) Thuthukisa i-lubricity kanye nepulasitiki, uthuthukise ukusebenza kahle; sebenzisa udaka oluthuthukisiwe nge-cellulose ether, okulula ukwakha, longa isikhathi sokwakha futhi kunciphisa izindleko zokwakha.
(3) Ukugcinwa kwamanzi okuphezulu kakhulu kwe-cellulose ether yezitini ezimunca amanzi aphezulu.
4. Isigcwalisi esihlangene
(1) Ukugcinwa kwamanzi okuhle kakhulu, isikhathi esivulekile esinwetshiwe kanye nokwenza ngcono ukusebenza kahle komsebenzi. Inamafutha amaningi futhi kulula ukuyixuba. (2) Thuthukisa ukumelana nokuncipha kanye nokumelana nokuqhekeka futhi uthuthukise ikhwalithi yendawo yokumboza. (3) Thuthukisa ukunamathela kwendawo yokubopha ukuze unikeze ukuthungwa okubushelelezi, okubushelelezi.
5. I-Tile Adhesive
(1) Kulula ukomisa izithako zokuxuba, azikho izigaxa, ukuthuthukisa isivinini sohlelo lokusebenza, ukuthuthukisa ukusebenza kokwakha, ukonga isikhathi sokusebenza nokunciphisa izindleko zomsebenzi.
(2) Thuthukisa ukusebenza kahle kokuthayela ngokwandisa isikhathi sokuvula futhi unikeze ukunamathela okuhle kakhulu.
6. Izinto ezizilinganisa phansi
(1) Ihlinzeka nge-viscosity futhi isebenza njenge-anti-settlement aid. (2) Thuthukisa ukudonsa kwamanzi futhi uthuthukise ukusebenza kahle kokugandaywa komhlabathi. (3) Lawula ukugcinwa kwamanzi kanye nokushwabana, unciphisa ukuqhekeka nokushwabana phansi.
7. Upende osuselwe emanzini
(1) Ivimbela imvula eqinile futhi yandise isikhathi sesitsha somkhiqizo. I-biostability ephezulu ngokuhambisana okuhle kakhulu nezinye izakhi. (2) Thuthukisa ukugeleza kwamanzi, unikeze ukumelana okuhle kwe-spatter, ukumelana ne-sag kanye nokulingana ukuze uqinisekise ukuqedwa okuhle kakhulu kwendawo.
8. I-wallpaper powder
(1) Chaza ngokushesha ngaphandle kwama-clumps, alungele ukuxutshwa. (2) Nikeza amandla ebhondi ephezulu.
9. Ishidi likasimende elikhishiwe
(1) Inokubambisana okuphezulu kanye nokuthambisa futhi ithuthukisa ukucutshungulwa kwemikhiqizo ekhishwe. (2) Thuthukisa amandla aluhlaza, ukhuthaze umphumela wokwelapha we-hydration, futhi uthuthukise isivuno.
10. Udaka oluxubekile
Imikhiqizo ye-HPMC yodaka oluxutshwe ngodaka ingcono kunemikhiqizo evamile odakeni oluxutshwe ngomumo, iqinisekisa ukuthi izinto zikasimende ezingaphili zigcwele amanzi ngokuphelele, okuvimbela ngokuphawulekayo amandla ebhondi ukuthi angabangelwa ukomiswa ngokweqile, kanye ne-Crack ebangelwa ukuncipha kokuqina. I-HPMC futhi inomphumela othile wokungenisa umoya. Umkhiqizo we-HPMC wodaka oluxutshwe ngaphambili unenani elifanele lokukhipha umoya, ukufana namabhamuza amancane, okungathuthukisa amandla nokugcotshwa kodaka oluxubekile. Umkhiqizo we-HPMC osetshenziselwa ngokukhethekile udaka oluxubekile unomphumela othile wokubuyisela emuva, onganweba isikhathi sokuvula udaka oluxutshwe ngomumo futhi unciphise ubunzima bokwakha.
Uma unentshisekelo ku-HPMC yethu, sicela usithumele i-imeyili:sales@kimachemical.com
